Abstract
A touch panel including a substrate, at least one touch-sensing unit, at least one connecting pad, at least a testing line, at least one ESD protection circuit, and a first isolation layer is provided. The touch-sensing unit is disposed on the substrate. The connecting pad is disposed on the substrate and electrically connected to the touch-sensing unit. The testing line is disposed on the substrate, electrically connected to the connecting pad, and extends to at least an edge of the substrate. The ESD protection circuit is disposed in the edge of the substrate and electrically connected to a ground voltage, wherein a vertical projection of the testing line to the substrate and that of the ESD protection circuit to the substrate is at least partially overlapped. The first isolation layer is disposed between the testing line and the ESD protection circuit.
